Linuxカーネルはmemmapパラメータ*）を使用して、さまざまなユースケースに合わせてメモリ領域を手動で指定します。 Q：違いは何ですか？予約済み記憶（memmap=nn[KMG]$ss[KMG]）と保護されるメモリ（memmap=nn[KMG]!ss[KMG]）？ つまり、カーネルはこれをどのように処理し、いつ使用されますか？ に関しては、予約されたメモリが保護されたメモリとしてリストされていると/proc/iomem思います。そうですか？ReservedRAM buffer *) テキストでいっぱいではなく、リンク可能な良い参照ページが見つからなかったため、リンクを添付しました。カーネル文書: memmap=exactmap [KNL,X86] Enable setting of an exact
E820 memory map, as specified by the user.
Such memmap=exactmap lines can be constructed based on
BIOS output or other requirements. See the memmap=nn@ss
option description.
memmap=nn[KMG]@ss[KMG]
[KNL] Force usage of a specific region of memory.
Region of memory to be used is from ss to ss+nn.
If @ss[KMG] is omitted, it is equivalent to mem=nn[KMG],
which limits max address to nn[KMG].
Multiple different regions can be specified,
comma delimited.
Example:
memmap=100M@2G,100M#3G,1G!1024G
memmap=nn[KMG]#ss[KMG]
[KNL,ACPI] Mark specific memory as ACPI data.
Region of memory to be marked is from ss to ss+nn.
memmap=nn[KMG]$ss[KMG]
[KNL,ACPI] Mark specific memory as reserved.
Region of memory to be reserved is from ss to ss+nn.
Example: Exclude memory from 0x18690000-0x1869ffff
memmap=64K$0x18690000
or
memmap=0x10000$0x18690000
Some bootloaders may need an escape character before '$',
like Grub2, otherwise '$' and the following number
will be eaten.
memmap=nn[KMG]!ss[KMG]
[KNL,X86] Mark specific memory as protected.
Region of memory to be used, from ss to ss+nn.
The memory region may be marked as e820 type 12 (0xc)
and is NVDIMM or ADR memory.
memmap=%-+
[KNL,ACPI] Convert memory within the specified region
from to . If "-" is left
out, the whole region will be marked as ,
even if previously unavailable. If "+" is left
out, matching memory will be removed. Types are
specified as e820 types, e.g., 1 = RAM, 2 = reserved,
3 = ACPI, 12 = PRAM.

sources.list.dフォルダが存在し、ファイルと共に存在することを確認しましたparrot.list。私のPythonのバージョンはPython 3.9.2次のとおりですparrot.list。 ## This file provides the default APT repositories for Parrot Security
## These repositories are used to fetch new software and system updates
###############################
## Default Parrot Repository ##
###############################
## The 'parrot' repository provides all the Parrot software considered
## stable and tested.
##
## the main suite provides the base system plus all the software released
## under a free and open source license compatible with the Debian guidelines.
##
## the contrib suite provides additional free software that depends on third
## party software not provided by the main suite. it usually means that such
## packages depend on non-free software.
##
## the non-free suite provides additional packages that don't comply with
## the Debian Free Software Guidelines. They are mostly proprietary software.
deb https://deb.parrot.sh/parrot parrot main contrib non-free
######################
## Security Updates ##
######################
## The 'parrot-security' repository provides time sensitive security updates
## that have to be delivered to end users as fast as possible
##
## this repo should always be enabled in your system
##
## we strongly recommend to NOT use mirrors for this repo, but only
## access security updates from our official domains or CDNs.
##
## a mirror server could take too much time to fetch an important update,
## leaving you without security updates for a timespan outside of our control
deb https://deb.parrot.sh/direct/parrot parrot-security main contrib non-free
###############
## Backports ##
###############
## The stable repository contains software that is considered stable the day of
## the release. such packages receive only security and stability updates that
## don't introduce new features and don't drop old ones.
##
## the 'backports' repository provides feature updates to many packages, and
## even external software that was originally excluded from the stable release.
##
## disable it if you prefer stability and reliability over bleeding edge features
deb https://deb.parrot.sh/parrot parrot-backports main contrib non-free
#######################
## Updates / Testing ##
#######################
## The 'parrot-updates' repository provides updates before they are made available
## to 'parrot'. this repo is mostly meant to be used by developers and beta testers
## to extensively test updates before they are migrated to the main repository
##
## we suggest not to enable it, as it may introduce untested bugs and make the
## system unstable. updates are delivered as fast as possible (within a week)
## so you are not missing anything important with this disabled (unless you are a dev)
#deb https://deb.parrot.sh/parrot parrot-updates main contrib non-free
##############################
## Source Code Repositories ##
##############################
## These repositories provide the debian source artifacts of the packages
## in the corresponding repos in the form of dsc files and the corresponding
## tarballs
##
## you only need these repositories if you intend to download the source code
## of a package and re-compile it yourself with debian-compliant build tools
#deb-src https://deb.parrot.sh/parrot parrot main contrib non-free
#deb-src https://deb.parrot.sh/parrot parrot-security main contrib non-free
#deb-src https://deb.parrot.sh/parrot parrot-backports main contrib non-free
#deb-src https://deb.parrot.sh/parrot parrot-updates main contrib non-free
##########################################################
## How to configure mirror servers for faster downloads ##
##########################################################
## The Parrot system is configured by default to use the central
## parrot archive directors. The Parrot directors are special servers that
## collect all the requests of the users and redirect them to the nearest
## download server available for the user who made the request.
##
## The Parrot Mirror Network is secured by centralized digital signatures
## and the mirrors can't inject fake updates. If an evil mirror tries to inject
## a fake package, Parrot OS will automatically refuse to download and install it.
##
## To configure a mirror, you have to replace the original URL with the URL
## Provided by the mirror
##
## Example:
## If you live in Italy and you want to take advantage of the GARR mirror,
## Replace
## deb https://deb.parrot.sh/parrot parrot main contrib non-free
## With
## deb https://parrot.mirror.garr.it/mirrors/parrot parrot main contrib non-free
##
## IMPORTANT NOTES:
## do NOT use mirrors for the parrot-security repository. use them
## exclusively for 'parrot', 'parrot-backports' and 'parrot-updates'
##
## LIST:
## A full and updated list of official mirrors is available here:
